 Bienvenue à tous !__________________Raphael St-Gelais (Cornell Nanophoton
 ics Group) Radiative heat transfer between objects separated by subwavele
 ngth distances offers unprecedented opportunities for energy generation an
 d heat flow control applications. In the optical near-field\, heat transfe
 r can occur through evanescent coupling of thermally excited infrared surf
 ace resonances (i.e.\, plasmonic or phononic surface resonances). This hea
 t transport mechanism can overcome the classical far-field radiation limit
  (i.e.\, Stefan-Boltzmann law) by several orders of magnitude\, while occu
 rring over a quasi-monochromatic frequency range. These unique characteris
 tics could enable new exciting applications\, such as near-field thermopho
 tovolatic energy generation\, or active heat flow control devices such as 
 thermal rectifiers and thermal transistors. I will review these prospectiv
 e applications and present our recent work [1]\, in which we achieved the 
 first experimental demonstration of near-field radiative heat transfer bet
 ween integrated nanostructures. [1] Demonstration of Strong Near-Field Ra
